The Investigation team of the Interstate Aviation Committee has completed the investigation of the accident with Mi-2 RA-23721 helicopter owned by "Convers Avia Airline" CJSC occurred in Khanty-Mansijsk Autonomous District on July 10, 2014.
The accident with Mi-2 RA-23721 helicopter was caused by performng flight at the altitude 10-12 m not ensuring safe operation over obstacle that resulted in rotorcraft collission with aerial PTL wires.
It wasn't possible to determine exactly the cause of operation at the altitude 10-12 m but most probably the pilot during take-off distracted from helicopter piloting and outside monitoring due to the possible drop of HP iPAQ Travel Companion pocket PC from its attaching point used by PIC as non-standard navigation device.
Lack of aerial PTL wires marking could be the contributing factor.
The appropriate safety recommendations based on the investigation results were developed.
